Participants

Reaction Steps

In the glovebox, N-((6-bromopyridin-2-yl)methylene)-2,6-diisopropylaniline (1.392 g, 4.03 mmol) is combined with 5-(but-3-enyloxy)-2,4-dimethylphenylboronic acid (1.000 g, 4.03 mmol) and KOH (0.678 g, 12.1 mmol) and dry THF (40 mL) is added. Palladium(I) tri-tert-butylphosphine bromide, dimer [PtBu3)PdBr]2 (0.062 g, 0.040 mmol) is added and the reaction mixture is stirred for five hours, removed from the glovebox, and ether (100 mL) is added. The solution is washed with water (50 mL) and then brine (50 mL), dried over magnesium sulfate, filtered, and solvents removed by evaporation. Yield=1.86 g of orange sticky oil. The product is used without further purification.
